TIRE-BO LT CUTTER.

SPECIFICATION forming part of Letters Patent N 0. 554,504, dated February 11, 1896.

Application filed December 6, 1895.

To all whom it may concern.-

Be it known that I, JOHN CAMERON CLINCH, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Tire-Bolt Cutters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in tire-bolt cutters. It is designed to remove the end of the bolt by a clear smooth out. The instruments now in use for that purpose, being in the form of pinchers, do not make a smooth out, but leave a rough sharp ridge, which has to be removed by a file after the head is cut off to prevent damage to the sponge used in washing the wheel.

In the drawings herewith accompanying and forming a part of this application, Figure 1 is a perspective view of my device shown in position on the carriage-wheel rim. Fig. 2 is a detail view of the knife and its operatinglever removed from the rest of the tool, and Fig. 3 is a detail View showing the adjustable clamping-jaw.

Same letters refer to like parts.

In said drawings, A represents a clampingjaw, the inner side B of which is concaved to conform to the convex surface of the inner edge of the wheel-rim. In said jaw is a 1ongitudinal groove 0 and an opening D adapted to receive the nut E on the end of the rimbolt F. The thickness of the jaw at this point should be equal to the thickness of the nut. Slidin gin the longitudinal groove before mentioned across said opening D is a bolt-cutter G. The bolt-cutter G has a ratchet H on one edge. Pivotally mounted in the jaw is a lever I, having on its lower end teeth J adapted to engage said ratchet, wherebya reciprocat- Serial No. 571,245. (No model.)

ing motion maybe imparted to said cutter. The jaw A has integral therewith a transverse arm K, in the top of which is a series of notches L. Mounted on said arm is an adjustable jaw M, having a slot N therein, through which said arm is adapted to pass, and mounted therein is a cross-bar or hearing P adapted to engage one of said series of notches. The removable clamping-j aw M has a lever-handle O, by means of which a firm grip can be taken of the carriage-wheel rim. For convenience the end of jaw A is cut away, as seen at Q, to enable the operator to see the bolt while being cut and to prevent clogging of the cutter.

The operation of my improved device is as follows: The tool is placed over the carriagerim, the jawA being on the inside of the rim. It is then adjusted by placing it so that the bolt-head and nut project through the openingD. The jaws are then set, the lever thrown back, forcing the knife forward over the top of the nut and cutting off the head of the bolt close to the nut and in a plane parallel with the surface of the nut.

Having thus described my invention and its use, I claim In a tool for removing the ends of tire-bolts, a clamping-jaw having an opening therein to receive the nut and bolt end, a longitudinal groove therein, a bolt-cutter mounted in said groove and adapted to slide over said opening, means for imparting a reciprocating motion to said cutter, and a clamping-j aw adapted to hold said first -,named jaw upon the wheel-rim, substantially as and for the purposes set forth.

In testimony whereof I afiix my signature, in presence of two witnesses, this 3d day of December, 1895.

JOHN CAMERON OLINOH. 'Witnesses:
